php <defunct>

[supahfly]

HI There

I am currently suffering from DOS attacks.
I am not so experienced in php.
But it seems that somebody is accessing php with the main user of the site and not as nobody.
I see: php /home/user/public_html/index.php
all of these processes show up as php <defunct> ...

What can I do ?

Thanks

Is there a way to only allow the main user to operate from the localhost ?
I thhink that way we also allow the main user to use phpmyadmin, right ?
